"We have to be prepared to walk out", she said to applause during a Sky News interview today.

"They are adopting an aggressive negotiating position, which can only be met by strong leadership on behalf of Britain", she will say according to a pre-released copy of her speech.

May and Labour leader Jeremy Corbyn appeared in what was billed as a debate although they were interviewed and answered questions from an audience separately. "No deal is better than a bad deal", she said.

Answering questions on the interview after launching Labour's race and faith manifesto in Watford, Mr Corbyn said: "I didn't have the exact figure in front of me, so I was unable to answer that question, for which obviously I apologise".

Speaking ahead of a BBC Question Time special on Thursday, in which he will question both Prime Minister Theresa May and the Labour leader, Dimbleby said nothing in this election should be taken for granted despite the Tory lead in the polls.

Jeremy Corbyn has said he "will not tolerate" the abuse aimed at Woman's Hour presenter Emma Barnett following his vehicle crash interview.

And he wondered aloud whether European leaders at the Brexit negotiation table would not look at Theresa May's recent policy U-turns and label her a "blowhard who collapses at the first sign of gunfire".

Labour leader Jeremy Corbyn finished his appearance on BBC1′s The One Show's by giving the presenters a jar of his home-made jam.

He firstly responded that it would "cost a lot to do so, we accept that".

Ms May was heckled and laughed at by some members of the audience at Monday's TV appearance when discussing her education policy, and when Paxman asked whether the European Union would see her as a "blowhard who collapses at the first sign of gunfire" after she softened her plans on old age care. That is about Brexit, but it's also about facing up to domestic challenges.

She will also present the Conservatives as the best party to defend Britain's sovereignty during the negotiations, and to push down immigration numbers - the two key concerns for most pro-Brexit voters, including those in traditional Labour areas.

The two fundamental problems he has as leader of the Labour party, are 1) that many of his views clash with the policy of the party he leads, and 2) that the overwhelming majority of Labour MPs in the last parliament and of those who will serve in the next do not want him to be their leader. The Tories dispatched their genial attack dog David Gauke on to social media to weigh in on Corbyn's backbencher comments on the IRA and the Falklands but, while the man aiming to be PM will continue to face questions over some very unwise remarks, he didn't fall apart in the way his opponents had hoped.
